TROLLEY.

Specification of Letters Patent.

Patented April 23, 1907.

Application filed June 906- serial 323,436.

, being disassociated in event of the trolleywheel jumping the trolleywire.

. The invention aims to provide a harp similar to the ordinary type ofharp carried by the trolley poles of electrically operated cars, and inconnection with the trolley-harp, I employ available means forpreventing the harp from leaving the conductor or trolley wire in eventof the trolley wheel being disconnected from or jumping the wire.

In constructing my improved harp, l have considered the possibility ofinterference by wire hangers, crossings, and overhead work that may tendto break and interfere with the positive operation of my improved.mechanism, therefore, I have constructed the harp, whereby a portion ofthe same may recede without breaking or injuring theoverheadconstruction which supports a trolley wire. In this connection,the invention dispenses with the trouble and watchfulness on the art ofa car operator heretofore necessitate by the construction of the trolleywheels and harps. To this end, I have devised a trolley-harp havingspring-held arms which normally extend above the trolley wire.

The detailed construction of my im roved harp will be presentlydescribed an then specifically pointed out in the claims.

Referring to the drawing forming part of this specification, likenumerals of reference desi nate similar parts in the several views, in w'ch:

Figure 1 is a side elevation of my improved trolley harp, Fig. 2 is aplan of the same, Fig. 3 is a vertical sectional view taken on line x:z:of Fig. 1, and Fig. 1 is a longitudinal sectional view of a'portion ofone of the side arms of my improved harp together with one of theyieldable fingers of the same.

My improved harp consists of a sleeve 1 adapted to fit upon the end of atrolley pole 2, said sleeve being secured thereon by a pin 3 orsimilarjfasteningimeans.,it The sleeve 1 carries two parallel arms 4similar somewhat to any ordinary harp. Between these arms is mounted atransversely disposed pin 5, upon which a trolley wheel 6 is journalled,said wheel having a prolonged hub 7 normally held centrally of the pin 5by springs 8, secured to the arms 4, as at 9.

The ends of the arms 4. are provided with angularly disposed extensions10 and with sockets 11. In said sockets are loosely mounted the ends ofrods 12, said rods being further supported intermediate their ends bysprings 14. The springs 1 1 surround depending pins 15 carried by therods 12, said pins extending through the extensions 10 and retainedtherein by cotter pins 16.

When the trolley wheel 6 is placed upon a trolley wire 17, the rods 12extend upwardly at an angle upon each side of said wire, and ellectuallyprevent the lateral displacement of the harp. As the harp passes undercross over wires, or trolley boards, such as are arranged under bridges,the rods 12 re cede and are returned to their normal position by thesprings 14, which rest upon the extensions 10. The arms 12 areindependently arranged and independently supported by their respectiverods 15 and springs 14, so that if an obstruction at one side of thetrolley only is met with one of the arms only will be depressed, therebyleaving the other arm in position to protect the harp and wheel fromlateral displacement. This is an important feature of the invention andadds materially to its e'l'l'iciency.

'Since a lateral movement of the trolley wheel 6 is possible by theconstruction herein shown and described, said wheel can readily adjustitself to a wire that may not be in di rect alignment with the pole 2.

The entire harp is constructed of strong and durable material especiallythe rods 12, which will be subjected to considerable wear and tear, bycontacting with the wire 17 and its hangers or supports.

Such changes in the size, proportion and minor details of constructionas are permissible by the appended claims may be resorted to withoutdeparting from the spirit and scope of the invention.

\Nhat I claim and desire to secure by Letters Patent, is

1. A trolley harp comprising a sleeve supported upon a trolley pole andwith spaced arms extending from the forward end and I provided withlongitudinal sockets interme above the line of the trolley wheel, andyieldable devices between said rods and the free ends of said arms.

2. In a device of the class described, a member having means forconnection to a trolley pole and spaced longitudinal arms having socketsintermediate their ends and with apertures at their free ends, a trolleywheel journalled between said arms, rods bearing at one end loosely 1nsald sockets and extending at their free ends above the line of thetrolley wheel, pins depending from said rods and extending through theapertures in said spaced arms, and springs operating between said rodsand arms and maintaining said rods yieldably in their upward position.In testimony whereof I afliX my signature in the presence of twowitnesses.
